The brothers return in a brand new adventure on the high seas. Set sail with Mario and Luigi towards Kapitarbora (half ship, half island) and travel the wide world of Konektania. Let yourself be catapulted from a cannon on Kapitarbora to islands ranging from tropical rainforests to bustling cities, explore them and embark on adventures. Meet new friends along the way, like Connetta and Wattz (not a pig by any means), and encounter familiar Mushroom Kingdom characters like Peach and Bowser who may help you on your journey. You'll be relying on the brotherly bonds between Mario and Luigi. Use brother moves to overcome obstacles during your explorations and powerful, dynamically alternating pair attacks in turn-based battles. You'll need the full range of this brotherhood to succeed.
